WRAPPING-MACHINE Specification of Letters Patent.

Patented Dec. '8, 1908.

Application filed April 6, 1907. Serial No. 866,666.

To all whom it may concern:

Be it known that I, MILTON H. BALLARD, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Wrapping-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characteis on the drawings representing like parts.

This invention relates to wrapping machines of the ty e represented in Letters Patent #516,136, dated March 6, 1894, and in my application for Letters Patent filed February 9, 1906, #300,331, and particularly'to the printing-device for printing the web of aper-which is fed forward and severed to orm the wrap ers.

The object o my invention is to provide a printing apparatus, whereby an electrotype or other form of printing plate, as contrasted with a rubber stamp, may be employed, a;nd the web of paper printed at a particular part thereof, so that when subsequently severed to form a wrapper the printing will occupy a certain position thereon. Also, to provide means for adjusting the printing apparatus with respect to the paper, so that it Wlll operate to print the paper at different points, to provide for forming from the web of paper wrappers of different lengths, with the printing centrally disposed on the wrappers.

My invention comprehends the employment of a web printing apparatus and means for moving it with respect to the paper, and means for operating the printing-mechanism to print the paper, while the apparatus is being moved along and the paper is held at rest; also the employment of means for adjusting the printmg-apparatus with respect to the paper.

Figure 1 shows in side elevation a sufficient portion of a wrapping machine embodying my invention to illustrate the same. Fig. 2 is a plan view of the parts shown in Fig. 1. Fig. 3 is a side view of the printingapparatus and means for operating it.- Fig. 4 1s a vertical sectional detail taken on the dotted line 4-4 Fig. 1. Fig. 5'is a detail showing the frame of the printing-apparatus and its operating shaft. Fig. 6 is an enlarged side view of the printing-a paratus, the frame being shown 1n vertlca section. Fig. 7 is a vertical longitudinal section of the unting-apparatus. Fig. 8 is a detail of the means for operating one of the inking rolls. Fig. 9'is a detail to be referred to.

41, 42 represent -a-pair of feeding-rolls for the paper, which are adapted to' be operated intermlttingly to feed forward predetermined len the of aper for the wra pers. The two fe ing-rol s 41, 42 are geare together at one end, so that one of the rolls may be used to drive the other roll. To the lowermost roll 42 which is employed as the drivingroll, a clutch-member 60 is secured, and a clutchmember 61 is provided, which is movable into and out of engagement with said member 60 and which is also rotatable. The clutch-member 61 is connected with or secured to a spiral gear 64, which is en aged and driven by a spiral gear 65, secure to-a shaft bearing a pinion 53, which is engaged by a rack-bar 54, connected by alink with an upri ht arm 55, pivoted, at its lower end, to the frame, and which has extended from it, at or near its lower end, a curved slotted extension, to which is adj ustably connected one end of a bar 57, which is connected by an eccentric to the main shaft f As the shaft f 5 revolves the rack-bar 54 is reciprocated longitudinally and the pinion is reciprocated rotarily and the spiral gear 65 likewise reciprocated rotarily and the spiral gear 64 is moved along on its su port and isalso-rotated, to thereby move the clutch-member 61 into engagement with the fixed clutch-member 60, and to rotate it, to rotate the feed-roll 42. By changing the connection of the bar 57 with the slotted extension the length of stroke of the rack-bar may be varied in order that the feed-rolls may be operated to feed forward a greater or less length of paper to provide for the production of wrappers of different lengths or sizes. The feed-rolls, however, may be operated by any other means, as far as my resent invention is concerned, or'in lieu t ereof any other means may be employed for intermittingly feeding the aper.

T e web of aper which is fed forward by the feeding-r01 s is severed to form the wrappers, and, as herein shown, 306 represents a cross-head which carries the knife, the opposite enils of which are connected by links 310 to apair of arms 312, secured to a rock-shaft 313, and an upright rod 70 is connected to one of said arms 312, which is moved up and down to thereby rock the shaft and move the arms and raise and lower the cross-head. The lower end of the rod 70 is connected to one end of a lever 71 pivoted at 72, the opposite end ofwhi'ch is connected to the lower end of a rod 73, the upper end of which is engaged by a cam secured to the driving shaft The knife may be raised and lowered by any other means, so far as m present invention is concerned, or in lieu t ereof any other means may be employed for severing the paper to form the wrapper.

The printing-device for the paper, as herein shown, consists of a web prmting apparatus; and means are provided for moving it with respect to the paper, while the paper is at rest. 1 represents the main frame of the rinting-apparatus, which consists of a boxiike structure, constructed and arranged to provide bearings for the o crating parts. 2 represents the type-cylin er and 3 the impression-roll. The impression-roll is journaled in a yoke 4, whic is pivoted at 5, and which is yieldingly held down by a spring arrangpd in a suitable sup ort.

T e inkingglaipparatus or the type cylinder comprises in g-rolls 7, 8, 9, 10, 11, 12 and 13 of usual construction and an ink-reservoir 14.

A toothed gear 15 is secured to the shaft 21, which engages a bevel-gear22, secured to the shaft j, The pinion 16 also engages.

and drives a toothed gear 23, secured to the shaft of the inking-r0118, and another toothed gear 24 on said s aft engages a pinion 25 secured to a shaft 26. A cam is also secured to said shaft 26, which is adapted to 0 erate' the ink-spreading rolls, 9, 10 and 11, t e actuating levers for said rolls 9 and 11 being connected together and the actuating levers for the rolls 10' and 11 having laterally extended pins, which enter a groove or grooves in said cam. The shaft 26 also has secured to it a cam 28, see Fig. 8, which is adapted to move a frame 29, bearing the inking-roll 12, so as to move said roll into en agement with the ink-roll 13, a spring, whic 1s connected to said frame, operating to move said roll in the opposite direction, out of engagement with said roll 13 and into engagement with the inking-r0118. The shaft 26 also bears an arm 30, which, durin each revolution thereof, engages a star w eel 31, secured to the shaft of the ink-roll 13, for the lpurpose of intermittingly rotating said ro As the shaft f revolves the several cooperatin parts of theprinting-mechanism are cause to rotate and to otherwise operate. The type-cylinder 2 is provided with a typelate 110 of any suitable width but of a len t to extend but part way around the cylmder, so that during a part of the revolut1on of the cylinder the aper will be printed, and during the remain er of the revolution the paper will be disengaged in order that it may be moved along by the paper feedingdevice.

When the typelate disengages the paper the impression-r01 3 will not act to press the paper down onto the ty e-cylinder for the reason that an adjustabie stop-pin 32 will strike the frame and thereby limlt its downward movement.

As it is designed and intended that the printing-mechanism shall print the paper, While the paper is at rest, the entire printmgapparatus is made movable with respect to t e paper, and is adapted to operate to rint the paper while movin along; and, t ereafter, while the type-p ate disengages the aper the printing-apparatus is returned to 1ts normal position, preparatory to again moving alon and printing the paper. To provide for t us reciprocating the printingap aratus it is provlded with rolls 33, any sultable number being employed, which are arranged torun on a pair of tracks 34, which are rovided on the frame.

0 reciprocate the rinting-apparatus a pinion 35 1s secured to t e shaft which engages an internally toothed mo 36, having an arm 37 extended from it, which is pivotally or otherwise connected to the frame of the printing-apparatus. The rack 36 has an ear 38 on its lower edge, which extends downward and which hasa rib 39, projected from it laterally, which is adapted to engage a pin 40. As the pinion 35- revolves the rack is moved first in one direction and then in the opposite direction'and the rib moves along first above the pin 40 and then below said pin, the rack thereby rising at the com letion of its stroke in one direction and fal g at the completion of its stroke in the other di- 110 rection. It is obvious, however, that other means than that herein shown may be em-' ployed for reciprocating the printing-apparatus.

The distance traveled by the printing-ap 115 aratus in each direction, corresponds to or is at least as great as the length of the typeplate, so that while moving 1n one direction the type late will engage and print the apparatus by which it may be caused to occupy different positions with respect to the paper, so as to print the paper at the proper place in order that when the paper is severed the printed portion will occupy a central position on the severed portion or wrapper; and such adjustment is necessary to provide for printing the paper so as to thus centrally dispose the printin on the severed portions or wrappers of di erent sizes. To accomlish this result the printing apparatus is adustably connected with the means employed for moving it back and forth. This adjustment does not vary the extent of movement of the printing apparatus, but merely varies the positions ofthe printing-apparatus relative to fixed points at the beginning and end of its movement.

The means employed for moving the printing-apparatus back and forth are connected to a bar 80 and the printing-apparatus is adjustably connected with said bar. As herein shown, the arm 37 is loosely connected to said bar 80, and said bar is shaped to fit a dovetailed or other shaped recess in the frame of the printing-ap aratus, so that said frame may be moved al ong on said bar 80, and to hold the frame fixed in any position it may be set on said bar 80, a sliding-block 81, see Fig. 9, is fitted in a diagonally arranged hole in the frame of the rinting-apparatus, which is movable toward and from the bar 80 by means of a hand-screw 82 or other suit able means. Thus, to adjust the rintingapparatus the hand-screw will be oosened and the printingapparatus then moved along with respect to the bar 80, to the desired point, and then said hand-screw will be tightened and the printing-frame thereby secured to the bar 80. Thus, in the operation of my device, the pa er is first moved forward while the type-p ate disengages it, and the printing-apparatus is returned to its normal position or starting point, and then, while the paper is at rest, the printing-apparatus is moved in the op osite direction with respect to the paper an the printing-mechanism thereof 0 crates to print the paper.

Having thus d I claim as new and desire to secure by Letters Patent is 1.
